Enable the AllowSelectRowByClick property to allow users to select and deselect rows by mouse clicks, tap gestures, and keyboard shortcuts. To select a range of rows, users should hold down the Shift key and click the first and last rows in the range. To add/remove a row to/from selection, users should hold down the Ctrl key and click the row.

You can use the GridRowClickEventArgs.ShiftKey and GridRowClickEventArgs.CtrlKey event arguments to define whether the Shift or Ctrl key was pressed when a user clicked rows.
